Spec-Driven Development (SDD) Is Replacing Vibe Coding

SDD has emerged as the structured answer to vibe coding's failure mode (plausible code that drifts from intent as projects scale). The method: write an executable, version-controlled spec first, derive an implementation plan, break it into atomic tasks, then generate code. Every major AI coding tool — Claude Code, Cursor, GitHub Spec Kit, AWS Kiro, Google Antigravity — now ships its own SDD flavor. AWS Kiro reports real customer cases where 40-hour features shipped in under 8 human hours when authored spec-first.
